Light emitted from the light emitting member 100 may be incident vertically to the incident surface 203 of the guide member 200. Accordingly, in the light emitting member 100, the PCB 102 may be disposed to be perpendicular to the incident surface 203 of the guide member 200.

In the light emitting member 100, the PCB 102 may form an angle C of 0 to 90 degrees with respect to the window 42 of the door 40, and the guide member 200 may form an angle B of 0 to 90 degrees with respect to the window 42. The guide member 200 provided as a plate member having no bent portion may minimize the loss of light from the light emitting member 100.

Referring to FIG. 10, the guide member 200 may include a first portion 201 extending in a first direction from the incident surface 203, a second portion 202 bent from the first portion 201 and extending in a second direction, and a third portion 205 bent from the second portion 202 and extending in a third direction. The emitting surface 204 may be provided at one end of the third portion 205. Although not shown in the drawings, the guide member 200 may be formed as a plate member which has two or more bent portions and whose cross section is in the shape of a free curve.

Light emitted from the light emitting member 100 may be incident vertically to the incident surface 203 of the guide member 200. Thus, in the light emitting member 100, the PCB 102 may be disposed to be perpendicular to the incident surface 203 of the guide member 200.

Since the cooking room 20 maintains a temperature of about 200 degrees during cooking, the light emitting member 100 may be damaged by heat if it is disposed adjacent to the cooking room 20. Therefore, the light emitting member 100 may be disposed adjacent to the first panel 43 a as close as possible.

The light emitting member 100 may be disposed to be perpendicular to the plurality of panels 43. That is, the light emitting member 100 may be perpendicular to the window 42 of the door 40. The first portion 201 of the guide member 200 may extend in the first direction that is parallel to the window 42, and the third portion 205 may extend in the third direction that forms an angle D of 0 to 90 degrees with respect to the window 42.

Since the guide member 200 having a curved cross section can set the first direction to the third direction according to the position of the light emitting member 100, the light emitting member 100 can be disposed at any position in the door 40.

Meanwhile, by changing the cross section of the incident surface 203 and the emitting surface 204 of the guide member 200 to various forms, it is possible to facilitate arrangement of the light emitting member 100 and the guide member 200, and to increase the transmission efficiency of the guide member 200.

The incident surface 203 or the emitting surface 204 provided in the form of the inclined surface 207 may change the incidence direction and the emission direction of light so that the arrangement direction of the light emitting members 100 and the arrangement direction of the guide member 200 may change by appropriately changing the shape of the cross section of the incident surface 203 and the emitting surface 204.

The incident surface 203 provided in the form of the convex surface 208 may disperse incident light, and the emitting surface 204 provided in the form of the convex surface 208 may concentrate emitted light. In addition, the incident surface 203 provided in the form of the concave surface 209 may concentrate incident light, and the emitting surface 204 provided in the form of the convex surface 208 may disperse emitted light. Therefore, the light transmission efficiency of the guide member 200 may increase by appropriately changing the shape of the cross section of the incident surface 203 and the emitting surface 204.

The light transmitting efficiency of the guide member 200 may increase by performing various surface treatments on the emitting surface 204 of the guide member 200.
